OSHA ITA Establishment ID FAQ: What Safety Teams Need Before Upload

Each establishment in the ITA needs a consistent name, address, EIN, NAICS code, and size, and those details should match from year to year so submissions line up. You may use a number or code as the establishment name, as long as the submission includes a legal company name.

ITA upload work often stalls because establishment identity data is scattered across HR, safety, and finance.

Gather these first, and keep them with the record afterward:

• The coverage decision for each establishment: peak headcount, NAICS code, and which appendix applies
• The EIN used by each establishment
• The submitted file or payload and the ITA confirmation
• Notes on any corrections made after submission

Covered establishments submit injury data to OSHA's Injury Tracking Application (ITA) by March 2 each year for the previous calendar year; for 2026 data that is March 2, 2027 (29 CFR 1904.41). Three groups must submit: establishments with 250 or more employees that must keep records (300A data); establishments with 20 to 249 employees in an industry listed in Appendix A to Subpart E (300A data); and establishments with 100 or more employees in an industry listed in Appendix B (300A data plus 300 and 301 case data). Headcount means every individual employed at any time in the prior year, including part-time, seasonal, and temporary workers, and every submission includes the establishment's EIN.

1. Create or update each establishment profile.
2. Validate the identifiers.
3. Match names and addresses to last year's profiles.
4. Save the confirmation records.

Tip: Prepare the establishment name, address, EIN, NAICS code, employment count, hours worked, and form totals before upload.

Teams fix injury totals but leave establishment fields inconsistent across years.

Most ITA problems are establishment data problems: an old NAICS code, a parent-company EIN, or a headcount measured at the wrong level. The fix is to decide coverage per establishment in the fall, clean the EIN, NAICS, and address data then, and leave only validation and submission for February.

Analysts are measured on numbers leadership trusts, so document every input and assumption behind a rate or a total.

• Acquisitions and site name changes can make old ITA profiles hard to reconcile.
• Partially exempt establishments under 1904.1 or 1904.2 do not submit routinely, but must if OSHA notifies them in writing.

A chain renames its stores from street names to store numbers. In the ITA, the old “Main St” establishment and the new “Store 114” look like two sites. Updating the existing profile, rather than creating a new one, keeps the history in one place.

The ITA submission is built from the certified 300A (and, for Appendix B establishments, the 300 and 301), so every correction to the log has to be reconciled with what was submitted.

300log validates EIN and NAICS formats, produces ITA-ready CSV files for the 300A and for case data, and can authorize auto-filing of 300A data once you connect an ITA API token.
